Prepare your mind for these mind-blowing facts about outer space. Outer space can be viewed as a terrifying nightmare of infinite blackness that is extremely hostile to life. To put it another way, there are a lot of strange things about space. If you enjoy being surprised, all you have to do is glance up into the night sky and consider the size of the Earth in relation to the rest of the galaxy, or any of the other high-octane nightmare fuel on this list. These may be the creepiest of all the creepy things about space and the universe.
Hottest planet of solar system has a temperature of 450 degrees Celsius
Venus is the hottest planet in the solar system. The average surface temperature of this scorching planet is around 232 degrees Fahrenheit (450 degrees Celsius). Mercury, rather than Venus, is the closest planet to the Sun. Because Mercury lacks an atmosphere to regulate its temperature, it experiences extreme temperature swings. The atmosphere of Venus, on the other hand, is the thickest of all the planets. Venus is extremely hot because of its atmosphere, which traps heat.
The Earth’s time is faster than the time in space
Astronauts stationed in space lose around one second per week due to time dilation, a postulate of the theory of relativity referring to a discrepancy in the elapsed time measured by two observers. The Earth’s spin, its orbit around the sun, and the solar system’s velocity around the Milky Way all work together to reduce the amount of time we spend on the planet. Despite its insignificance, this second-per-week dilatation results in a loss of about a minute each year and more than 8.5 minutes every decade.
A planet made entirely of diamonds could exist
This is quite impressive in terms of facts about space. According to Yale University researchers, a rocky planet called 55 Cancri e. It is twice the size of Earth and has an eight-fold higher mass. It could have a graphite and diamond-like surface. It’s 40 light-years away in the constellation of Cancer, but it’s visible to the naked eye. NASA has taken a closer look at 55 Cancri e, an exoplanet that has been dubbed the “diamond planet” due to research that suggests it is carbon-rich. Even if we were able to reach these diamond exo-planets, they would be uninviting destinations.
The Smell of Space is Distinctive
Astronauts are usually accompanied by a weird, identifiable odor when they return from space. The odor is described as “sulphurous” and has been compared to gunpowder, seared steak, hot metal, and welding fumes by those who have been exposed to it.
The sky on Mars is reddish, with bluish twilights
Mars is known as the “Red Planet” due to its abundance of iron. This iron rusts when it comes into contact with the elements, turning it red all over. When the Sun is close to the horizon, the same fine dust particles scatter light differently.
In space, astronauts grow taller
During their time in space, astronauts can gain about 5 centimeters (2 inches) of height. This is due to the lack of gravity, which causes the discs in their spines to expand, making them taller. This was demonstrated by astronaut Scott Kelly’s 340-day stay in space. He grew taller than his twin brother when he returned to Earth.
Outer space is extremely cold
One of the most interesting facts about outer space is its extreme low temperature. This is close to absolute zero, or -459.67 degrees Fahrenheit (2.7 Kelvin), the lowest temperature ever recorded.
A massive hole hurtles through space at 5 million miles/hr black
In 2017, the Hubble Space Telescope discovered a black hole being influenced by gravitational waves. The black hole, which can eat anything in its path, will eventually break out from its galaxy and traverse the universe. Despite the fact that the anomaly is the size of a billion suns and has travelled at rates of around 5 million miles per hour, it is still predicted to be 8 billion light years away from Earth.
Milky Way Chunks are being Sucked Away
Something unidentifiable is sucking parts of the Milky Way galaxy, aka your home, away. It’s bigger than anything in the known universe. Researchers discovered a cluster of galaxies travelling at an incredible rate into a small piece of sky between the constellations Centaurus and Vela in 2009. This phenomena has been called “dark flow” by scientists in allusion to other cosmic mysteries such as dark matter and dark energy.
Someday, Night Sky will be Completely Black
The vista of the night sky from Earth will alter considerably as the Milky Way Galaxy merges with its surrounding galaxies. The rapid expansion will eventually force galaxies apart faster than light, obliterating the different products of the big bang and nullifying expansion measurement points.
Astronauts must recycle sweat and urine to live in space
Because space has a limited supply of water, astronauts must recycle their own waste. During his year-long mission, NASA astronaut Scott Kelly drank nearly 730 liters of recycled pee and sweat.
Meteors can strike Earth without warning
A meteorite burst over the Russian city of Chelyabinsk in 2013. Around 400 people were hurt, with the majority of the injuries being caused by broken glass from the explosion. According to conflicting sources, the missile was either a meteor shower or a single meteorite.
Global blackouts could be caused by solar super-storms
Facts about outer space: A coronal mass ejection (CME), often known as a solar super-storm, ripped through Earth’s orbit in July 2012, colliding with the STEREO-A probe. Earth would have absorbed the impact and terrible after-effects if the super storm had occurred one week sooner, according to Daniel Baker of the University of Colorado.
Neutron stars have a rotational speed of 600 times per second
Neutron stars are the densest and tiniest stars in the known universe, with a radius of about 10 kilometers (6 miles) and a mass a few times that of the Sun. They can rotate up to 60 times per second after forming from a core-collapse supernova star explosion, and due to their physics, they have been known to spin as fast as 600-712 times per second.
Gamma-Ray Bursts can Destroy Planets
If the qualities of gamma-ray bursts, which are massive explosions in faraway galaxies that emit out waves of gamma rays, are focused exactly towards the planet in question, they are capable of destroying entire worlds. Despite the grandiose nature of the scenario, Earth is quite safe. According to 2018 estimates, a gamma-ray burst will occur once every five million years in the Milky Way galaxy, although the radiation will most likely be far enough away to have little effect on life on Earth.
Callouses Slough off after a month in Space
Facts about Outer Space: In a Reddit AMA, Scott Kelly, the same astronaut who returned from the International Space Station with numerous genetic changes, revealed that foot callouses will eventually slough off in space:
Your feet’s bottoms become as soft as newborn baby’s feet. However, because I utilize the tops of my feet to get around here on the space station when using foot rails, the tops of my feet acquire rough alligator skin.
In a few billion years, the universe could literally explode
According to the “Big Rip” theory, a mysterious, pervading force known as “dark energy” would become so powerful in a few billion years that it will be able to tug every atom of Earth’s mass apart on an atomic level. In a report co-written with colleagues from the California Institute of Technology, Dartmouth physicist Dr. Robert Caldwell presented the apocalyptic scenario.
Nearsightedness can be caused by Space
Facts about outer space: Space travel has perplexing effects on the body, as astronaut Scott Kelly discovered during his year on the International Space Station. Deformation of an astronaut’s eyeballs after extended periods in space is one such impact, which could lead to long-term issues. The fluid surrounding the brain can build up to the point where the eyes expand and vision deteriorates dramatically.
Extended space travel can alter your DNA
Scott Kelly, an astronaut who spent a year on the International Space Station in 2016, returned to Earth two inches taller than when he left. Kelly’s sudden physical distinctions from his identical twin brother Mike, who is also an astronaut, were shocking. Kelly’s gut bacteria were completely different and his gene expression had altered, according to scientists who compared their DNA. Aside from growing two inches, Kelly’s gut bacteria were completely different and his gene expression had changed. The modifications were attributed to the stressors of space travel, which can create changes in a cell’s biochemical pathways. Kelly’s height returned to normal, but his other genetic mutations appear to be irreversible, implying that he and his brother are no longer identical twins.
Sounds can be heard in Space
Is space silent? Though conventional belief holds that deep space is a vacuum, interstellar dust is so dense in some locations that sound waves can travel through it. Humans, however, would be oblivious to these waves. The buzzing of a large black hole, the groaning of Earth as its crust shifts, and the lingering sound of the cosmos expanding are all possible noises in space.
As the universe expands, it cools
Facts about Outer Space: In 2013, astronomers measured the rate at which the universe is cooling by examining molecules in a gas cloud in a faraway galaxy. An international team of researchers was able to deduce a “fingerprint” of the universe’s cooling behavior using the CSIRO Australia Telescope Compact Array. They discovered that the cosmos had a temperature of –267.92 when it was half its current age. This is 2.35 degrees warmer than today’s –270.27 degree temperature.
Free-Floating Planets may outnumber the stars
In 2011, astronomers discovered a swarm of Jupiter-sized planets that were wandering in space, unattached to any star. The researchers theorized that the rogue planets were ejected from distant growing planetary systems, and that there could be twice as many of these free-floating worlds as stars. Free-floating planets smaller than Jupiter and Saturn could be even more abundant, given their lower mass permits them to be evicted from their systems more easily.
In Space, Water can start fires
Facts about Outer Space: Scientists experimented with “supercritical” water in 2014, a state of water that happens when it is compressed to a pressure of 217 atmospheres and heated to temperatures above 373 degrees Celsius. When combined with organic material, it produces a liquid-like gas with a burning effect but no flame. Supercritical water is frequently used by astronauts to dispose of waste.
Technically, the Earth is a part of the Sun
Is earth a part of sun? Despite the fact that the sun is 93 million miles distant from Earth, its atmosphere spreads far beyond not only this planet, but also Jupiter, Saturn, Uranus, and even Neptune. The helio-sphere is the bubble-like region of space dominated by the sun, and Earth is located within it. Humans are not just residents of Earth, but also of the sun.
Two same metals form a permanent bond in space
This amazing phenomenon is known as “cold welding,” and it occurs when the atoms of two metal pieces have no way of knowing they are separate. Because of the air and water between the pieces, this does not happen on Earth.
Galaxies can eat each other Galaxies can eat each other
Cannibalism is a tidal gravitational interaction in which a giant galaxy combines with a neighboring galaxy. The Whirlpool Galaxy, the Mice Galaxies, and the Antennae Galaxies are all examples of this process, which result in an irregular galaxy. Galactic Cannibalism should not be confused with Galactic Collision, which occurs when galaxies collide but keep their original shapes.
Tears don’t fall in Space
One of the most interesting facts about outer space is zero gravity. While astronauts can cry in space, the lack of gravity prevents tears from streaming down the face, instead clumping up and “conglomerating around the eyeball.”
These were some of the most interesting and mind-blowing facts about outer space. Even, there is much more to know about space, our research has not reached to the level, where we can answer every question about space. Hope so, our astronomers will bring every answer to us soon!
